Geogian diaspora

This month a friend and I looked into the results of Recognizing Speech on Android.  

In 2014 we created open source libraries and tools to facilitate usage of the Georgian language by Georgian speakers. One of these tools was Gismet, an Android application which can be used by Georgian speakers to train their Android smartphones to recognize their speech using PocketSphinx. The software was made freely available to the public and also open source on GitHub.


Since 2014 over 1,000 users have used the application to train the default language model to their voices. The location of the recordings is determined via GPS technology, and informed consent for the anonymous analysis of their voices is required as part of the software installation process.

  • Blue: IP geolocation

The resulting dataset of anonymous elicited training recordings is similar to a dataset obtained in an experimental setting. Below are a couple of spectrograms from the anonymous training recordings.

10.6.8 update spells Joy for Minimacs everywhere

If, after updating to 10.6.8 you get into a reboot loop, never fear the update is the same as every other update, except there is a step involving replacing the kernel.

This is very easy to do if you either (a) download it and save it on your Minimac before you update to 10.6.8, or (b) you have a mac formated USB key that you can copy it onto after your Minimac starts looping.

Here is the super-condensed minimal effort path to get you into Minimac heaven... (no not a dead Minimac, a running one), at least until Lion comes out.

English Noun Incorporation?

I was at a talk today with some Ojibwe data where invariably the claim that "English doesn't have incorporation" or at least incorporation of objects came up. We have "vacume clean" but generally we only incorporate the instrument. I remember a similar discussion coming up a few years ago in 2007 and I asked myself about apple picking. My colucators said, sure, but you can't say apple pick right? I thought about it a bit and came up with a linear string of words that might get google results. I remember I searched for "we apple picked" and found a few results, indicating to me that some people say it, generally when discussing their weekends. So, having my Android with me at the talk I googled again. This time I found a lot more examples than before, 394 to be exact, all of the first page clear examples with native speakers, speaking naturally.

I've heard this claim can be traced back to Baker 1988. When I got home I googled the claim "…
